The discussion centers on the safety of liquefied petroleum gas (LPG) and the potential for adding additives to make it unignitable and unexplosive at dilute pressures and concentrations. Participants highlight that LPG is a gas at standard temperature and pressure (STP) and becomes explosive when mixed with air, emphasizing the importance of understanding its lower and upper explosive limits. The conversation also explores the feasibility of using gaseous additives to enhance safety in case of leakage, particularly as LPG usage increases in transportation.
PREREQUISITESSafety engineers, chemical engineers, transportation safety professionals, and anyone involved in the handling or regulation of liquefied petroleum gas (LPG).
I never used LPG myself and do not suppose to use. I just curious how is it possible to make it safer if it will become more widespread on the transport. For example what gaseous additives could be used to make it uncombustible in a case of leakage.Borek said:I am not sure I understand your question. LPG at STP is a gas, and it becomes explosive when mixed with the air. Do you know what the lower and upper explosive limits are? Do you want to add something to the gas (produced by evaporation of LPG), or to the liquid?
